Abstract
The utility model relates to a take high rigidity drilling rod in antifriction area adopts CY120N take high rigidity drilling rod in antifriction area, can make the anti sulphur performance of whole of drilling rod obtain further improvement, simultaneously it has increased a slave station shoulder through meshing department in pin thread tip and box main aspects, and the slave station is takeed on then just in time to have and is detained the locate function on certain assisting to guarantee the accurate of master shoulder face and screw thread section interference fit and realize that in addition, the slave station shoulder also can bear the part -load in operating condition, and can improve the torsional strength of drilling rod, has guaranteed the security of drilling rod, the pin thread tip of drilling rod body is trapezoid table simultaneously, trapezoid table forms the enhancement section of pin thread tip, can improve the overall intensity of drilling rod. The both ends head of drilling rod is located to add and has been established many wear -resistant belt simultaneously, can prevent that tool joint department from being worn and torn to it can the normal connection to make between the drilling rod, is equipped with spiral groove on the drilling rod, can let silt in the well drilling pass through the recess and up carry, has reduced the resistance that the drilling rod received.
Description
Technical field
This utility model is related to a kind of high rigidity drilling rod with antifriction band, belongs to oil drill rocker technical field.
Background technology
In the drilling process of oil, natural gas, water source and mineral reserve, it is required for using drilling rod.Drilling rod passes through tool joint
Couple together, in During regular rotation, drilling rod will bear the effect of external and internal pressure, axial force, moment of flexure and moment of torsion simultaneously.
But common drill rod hardness is not high, after life-time service, tool joint frequently can occur failure accidents so as to become
The principal mode losing efficacy for drilling rod.
Content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one kind not easy to wear, and hardness is high, the good band of safety
The high rigidity drilling rod of antifriction band.
The purpose of this utility model is realized in：
A kind of high rigidity drilling rod with antifriction band, it includes drilling rod body, the periphery of the pin thread small end of described drilling rod body
It is provided with external screw thread, the inwall at the big end of box of drilling rod body is provided with female thread, the external screw thread of adjacent two drilling rods and interior spiral shell
Stricture of vagina engages so that two drilling rods couple together, and drilling rod body is up and down the two of externally threaded upper and lower ends and female thread
End opens up step surface, wherein shoulder based on the step of external screw thread lower end and female thread lower end, external screw thread upper end and female thread upper end
Step be secondary shoulder, the pin thread small end of drilling rod body is bucking ladder simultaneously, and described bucking ladder forms the strengthening segment of pin thread small end,
Described drilling rod body two ends are provided with a plurality of antifriction band, are further opened with some helical grooves on drilling rod body simultaneously.
The high rigidity drilling rod with antifriction band for this utility model has advantages below：
The high rigidity drilling rod with antifriction band for this utility model is by increased in the engagement place of pin thread small end and the big end of box
One secondary shoulder, secondary shoulder and main shoulder form dual stage shoulder structure, and main circular bead surface and thread segment produce certain interference fit,
And secondary shoulder then just has in certain auxiliary and anchors bit function, thus ensureing main circular bead surface and the standard of thread segment interference fit
Really existing, additionally, secondary shoulder in working order in also can bear fractional load, play certain overload protective function, and can also
The torsional strength improving drilling rod is it is ensured that the safety of drilling rod；
The pin thread small end of drilling rod body is bucking ladder simultaneously, and described bucking ladder forms the strengthening segment of pin thread small end, Ke Yiti
The bulk strength of high drilling rod；
Add a plurality of wear-resistant strip at the two ends of drilling rod simultaneously, can prevent from being worn at tool joint, strengthen simultaneously
Intensity at tool joint, so that can normally connect it is ensured that its safety between drilling rod, drilling rod is provided with spiral
Groove, can allow the mud in drilling well up convey by groove, decrease the resistance that drilling rod is subject to.

Specific embodiment
Referring to Fig. 1 to Fig. 3, this utility model is related to a kind of high rigidity drilling rod with antifriction band, including drilling rod body 1, institute
The periphery stating the pin thread small end of drilling rod body 1 is provided with external screw thread 2, and the inwall at the big end of box of drilling rod body 1 is provided with interior spiral shell
Stricture of vagina 3, the external screw thread 2 of adjacent two drilling rods is engaged with female thread 3 so that two drilling rods couple together, and drilling rod body 1 is outside
The upper and lower ends of the upper and lower ends of screw thread 2 and female thread 3 open up step surface, wherein external screw thread 2 lower end and female thread 3 lower end
Shoulder 4 based on step, the step of external screw thread 2 upper end and female thread 3 upper end is secondary shoulder 5.
Described main shoulder 4 and secondary shoulder 5 form dual stage shoulder structure, and main shoulder 4 and thread segment produce certain interference and join
Close, and secondary shoulder 5 then just has in certain auxiliary and anchors bit function, thus ensureing that main shoulder 4 and the interference of thread segment are joined
The accurate realization closed, additionally, secondary shoulder 5 in working order in also can bear fractional load, play certain overload protective function, and
And the torsional strength of drilling rod can also be improved it is ensured that the safety of drilling rod.
The pin thread small end of drilling rod body 1 is bucking ladder 6 simultaneously, and described bucking ladder 6 forms the strengthening segment of pin thread small end, permissible
Improve the bulk strength of drilling rod.
Described drilling rod body 1 two ends are provided with a plurality of antifriction band 8, and this antifriction band 8 can prevent from being worn at tool joint, with
When strengthen intensity at tool joint, so that can normally connect it is ensured that its safety, drilling rod simultaneously between drilling rod
Some helical grooves 7 are further opened with body 1, it is up defeated that described helical groove 7 can allow the mud in drilling well pass through this groove
Send, decrease the resistance that drilling rod is subject to.
